Electricians and plumbers stand out in “trades” because these jobs are fairly technical, while not particularly exhausting. A good plumber is always in high demand and can charge well for emergency interventions.
A plumber quoted me 1500 euros to install a swimming pool heat pump. I did it all myself with no prior experience and without the right tools in 8 hours. It cost me 300 euros worth of material. The guy would have made 1200 euros in a day. He was available 30 days from the time I called him, meaning he was quite busy.
Not saying that it’s the right call for everybody, but yeah right now, as a plumber or electrician who works in the high end of the trade, you make a decent living without the annoyances of office politics or fear of AI.
